Most developers need a spec to get started. I need a problem. Give me the context — what you're building, who it's for, what's broken or missing — and I'll figure out the rest. Frontend, backend, auth, data model, deployment. I don't hand off half a feature or wait to be told what to build next. I've shipped event processors, BYOK governance gateways, SaaS backends, and internal tools across multiple stacks. The through-line isn't the tech — it's taking ownership of delivery until the thing actually works. If you're a founder who has a clear problem but not a 40-page spec, or a product team that needs execution not hand-holding — that's the work I'm here for. Tech I work with Frontend: NextJS, React, App Router, Server Actions, Tailwind CSS Backend: Node.js, TypeScript, Express.js, NestJS, Golang, Gin, REST APIs, Webhooks Databases: PostgreSQL, MongoDB, Prisma, Redis, schema design, migrations AI & Integrations: OpenAI, LLMs, RAG pipelines, vector search, function calling, voice interfaces, third-party API orchestration, OAuth flows, webhook systems Auth & Security: JWT, RBAC, session management, secure server-side key handling DevOps: Docker, GitHub Actions, CI/CD, environment management, Git In short, I'm a Top Rated Senior Software Engineer, and a Web Developer for hire with a 100% Job Success Score :D
